  1. oops

    The battery was smaller than the one that was in my tractor before. I did not secure it properly which caused the battery to slide into one of the belts and it ate the battery. The bottom corner. The company had me verify the battery was the one I got from them. 3 days later I had a replacement battery I’m currently charging getting ready to put it back in the tractor. Only this time I’ll make sure it’s secure. Awesome company.

    This battery has sufficient power to start my lawn tractor. It is also thinner than previous batteries and fit in the battery compartment very easily. My only complaint is that the terminal holes on the battery were smaller than previous batteries I had. Nuts and bolts were supplied but were very small and seemed fragile. I had some older ones that I used that worked better and were stronger.

    Item was as expected

  19. CaroleLV

    Replaced a dead generator battery and put us back in service when needed during spring storms and tornado weather.

  20. anthony b.

    Easy to install. Smaller than old one but started the tractor.

  21. Customer

    I knew from reading reviews that the battery was small, but performance was great. So far 100% true! I put it in my ride on mower which had been in a cold garage all winter, turned key and it fired in seconds. Battery clearly has ample cranking amps, because the mower starts quicker than it ever has. Excellent value.

  22. Fattz

    Easy install just like a car battery. Lawn mower cranked right up. Cut the grass last weekend.

  23. steven ammons

    It worked perfectly for my lawn tractor. Will be buying another one for my lawn mower

  24. Rick Ryan

    Nice

  25. Tyebo

    Great battery for your lawnmower needs. One thing though it is on the small side but still works great.

  26. Louis A. Henderson

    Good price, worked well on generator.

  27. Lucille W.

    Battery is for my champion generator

  28. Joe Savino

    This little battery weighs about the same as the bigger lead acid one it replaced but is half the size. Starts my Cub Cadet riding mower, no problem. I put a piece of 5/4×6 pressure treated board on either side of it to fill the battery box. Modern batteries have come a long way. I’ll update when I see how it holds up.

  29. cogle1726

    Put it in my riding mower and it started right up. I thought it was kind of small when I put it in but it had the power needed.

  31. Jerry B. Craven

    it has started my mower a few times so cant complain

  32. Louis M.

    Hey All – This battery is rechargeable and has lasted me for 2 years with no issues and plenty of power to start my John Deere D100 , Craftmans, 19.0 42 6 speeder and McCulloch M12597 riding lawn mowers. It lasted the winter and still maintaining it’s charge if you are looking to buy, then buy this MMB and stopping wasting your money & time running to walmart and lowes. If your like me when you get on your riding lawn it needs to operate its not about the money it’s about saving save time and getting the job done. Peace

  33. Mark

    Exact fit for replacement of the battery on my generator. Seems to be better made than the original. Will see how long it holds up.

  34. liz 22 nd

Mighty max brings the battery backup back.
Arrived well packed in unopened sturdy box. Was replacement for identical Mighty Max battery I ordered 2 years ago. Taking 1 star off because didn’t include the needed terminal clips - was able to use the old battery’s clips
Same model fits in each of our four wheelers great product
Replacement for my Murray MT100 riding lawnmower. Murray does not make replacement batteries and you are on your own if the battery goes bad. Bought Murray MT100 in 2023, battery went bad in 1 year and all other Murray replacement batteries are LARGER so it won't fit.This Mighty Max Battery fit the MT100 fine and it starts it perfectly too.
Direct replacement for generac portable electric start generator. Works great.
Received really quick. Boxed well and fit great. Worked like a charm! I would definitely recommend this battery.
As an athletic trainer I rely on our water units every day to provide the water to our athletes. We have over 900 student athletes enrolled, and these units get used daily, so it is imperative these batteries are reliable. On a side note, I also use these batteries on my fishing kayak to power my fish finder. I can use my fish finder for about 20 hours before it turns off. These batteries are great! Highly recommend. I have not had any issues so I haven't spoken to customer service yet, but if they are as good as these batteries have been, I think I am in good hands.
Needed a replacement battery and the manufacturer wanted $50 whereas you only required $20. Made it worth it!
satisfy with price and easy installation.
Arrived in great condition comes with the bolts to attach the wire over all very satisfied
